摘要:
为了提高闸瓦磨损情况、闸瓦间隙变化的故障识别和诊断效率，从而使设备状态满足煤矿安全规程的各项具体要求。该文选用Daubechies5小波作为小波基，对提升机闸瓦间隙信号进行多分辨率分析，将突变信号进行多尺度分解，通过分解后的信号来确定突变信号的位置，通过分解后的3层高频重构图形可以具体清楚地确定突变信号的位置，实现提升机闸瓦间隙故障的诊断，对故障信号的位置进行较好地判断。
Abstract:
In order to improve the efficiency of fault identification and diagnosis of wear degree and clearance change of brake shoe, so as to meet the requirements of coal mine safety regulations. In this paper, daubechies5 wavelet is selected as the wavelet base to analyze the brake shoe clearance signal of hoist in multi-resolution, decompose the sudden change signal in multi-scale, determine the position of the sudden change signal through the decomposed signal, and clearly determine the position of the sudden change signal through the decomposed three-layer high-frequency reconstruction graph, so as to realize the fault diagnosis of the brake shoe clearance of hoist and the position of the fault signal Set to make a better judgment.
